CBS Chicago previously reported that the First Data-owned Money Network, one of the companies behind the new Ventra card, had an "F" rating with the Better Business Bureau due to receiving nearly 100 complaints over the last thee years. Among the complaints? That Money Network denied customers' disputes of clearly fraudulent debit card charges.

UPDATE (3/7/13): Since the CBS report was published, Money Network's BBB rating has been updated to a B+. According to a spokesman for First Data, the BBB "initially misclassified Money Network by business size, resulting in a low rating" and First Data worked with the bureau "to correct the error and to resolve all 97 complaints filed in their system over a span of three years."

According to CBS, the CTA expects it will save $5 million each year as riders switch to Ventra cards from temporary cards.
